Abstract
A paper cassette feeder and an image forming apparatus having the same are provided. The paper cassette feeder includes: a main frame; a loading unit on which paper is loaded; a first paper guide which is tilted up with respect to the loading unit; and a second paper guide which is disposed at the first paper guide in a turnable manner, and is tilted up with respect to the first paper guide according to a position of the second paper guide. Accordingly, a paper cassette feeder can be easily separated from an image forming apparatus when paper is jammed in a paper feeding path, so as to remove a paper jam easily.
Claims17
A paper cassette feeder for use in an image forming apparatus, comprising:
- a cassette frame;
- a loading unit disposed inside the cassette frame, to load sheets of paper;
- a first paper guide provided on the main frame, to guide the paper along a first paper feeding path, as the paper is picked up from the loading unit;
- and
- one or more second paper guides movably attached to the first paper guide, to rotate between a first position to open the first paper feeding path, and a second position to block the first paper feeding path, wherein,
- a through-hole is formed in the cassette frame adjacent to the first and second paper guides, through which paper is fed from another cassette feeder into the image forming apparatus, and
- when the paper is jammed in the through-hole, and the paper cassette feeder is pulled from the image forming apparatus to remove the jammed paper, the one or more second paper guides are pushed by the jammed paper and are rotated to a position for blocking the paper feeding path.
